Diagnostics system improvement of turn-to-turn short circuits of synchronous generator rotor winding

In the construction of monitoring systems and diagnostics of the hardly revealed defects of synchronous generators (SG), the most demanded methods are intellectual ones of digital signal processing. The method of quasi-reactive power determination is described in this paper by preparation of entrance data for intellectual diagnostics system of turn-to-turn short circuits of synchronous generator rotor winding. The offered formation method of reactive power input signals allows increasing sensitivity of the diagnostic system based on allocation nonviscous by means of the trained dynamic neural network, between specified excitation current defined on the basis of reactive power value and its real value.
